Is it possible to skip "A" page, rather than skipping to a page?

Please elaborate so we can get the full context of your question. Technically, when you "skip A page" you're skipping (advancing) to a (specific) page.

The reply by Brent above is true. When you want to skip page A you actually sending someone to page B, or to say it differently if you want your users not to see page A and want to see the page B instead, you need to set them to skip to the page B.

Of course, if you wish, you can also set some page behind the submit button and have the Next button set as invisible so that no one can see that page A - if that is what you are after.
